Gene expression in germinal center light zone, dark zone, and naïve B cells

ABSTRACT: Microarrays of gene expression in mouse germinal center B cells photoactivated in the light zone or dark zone, and of naïve cells for comparison. We used microarray data to identify genes differentially expressed by B cells in the light and dark zones of the germinal center. Light and dark zone cells were photoactivated in day 7 germinal centers and sorted by flow cytometry. Naïve splenic B cells(IgD+CD19+) were sorted for comparison.

Gene expression in human germinal center light zone and dark zone B cells

Project description:Microarrays of gene expression in human germinal center light zone and dark zone B cells sorted according to the expression of cell surface molecules CD83 and CXCR4 We used microarray data to identify genes differentially expressed by B cells in the light and dark zones of germinal centers from human tonsil specimens. Germinal center B cells (CD19+CD38+IgD-) were sorted from pediatric tonsil discard specimens into light zone (CXCR4hi/CD83lo) and dark zone (CXCR4lo/CD83hi) populations, from which RNA was extracted

RNAseq of germinal center B cells from Blimp-1-GFP reporter mice

Project description:RNAseq of germinal center B cells with different Blimp-1-GFP reporter level. Sorted germinal center populations were defined by their expression of Blimp-1-GFP reporter and the cell surface marker CD138 before they were further split into dark zone or light zone / dark zone like or light zone like cells based on their expression of the surface marker CXCR4 and CD83. We used RNAseq to find genes differentially regulated in various Blimp-1-GFP expressing germinal center populations from the spleen at day 10 after intraperitoneal immunisation with sheep red blood cells.

Single-cell characterization of transcriptomic heterogeneity in human tonsillar B-cell subsets

Project description:BFL-1 is an understudied anti-apoptotic protein that is upregulated in melanoma, certain forms of leukemias and lymphomas, and Epstein-Barr virus (EBV)-immortalized lymphoblastoid cell lines (LCLs). We have previously shown that BFL-1 is upregulated in LCLs through a viral-mediated chromatin conformation. However, BFL-1 is also highly expressed in uninfected B cells undergoing maturation in the germinal center. We therefore sought to determine the non-viral mechanisms underlying BFL-1 upregulation in B cells. Here, we characterized the chromatin landscape of maturing B cell subsets found in human tonsillar lymphoid tissue. While chromatin accessibility at the BFL-1 locus increases as naïve B cells enter the germinal center reaction, we found that BFL-1 expression during the transition from dark zone to light zone correlates with a significant increase in three-dimensional chromatin association between upstream enhancer regions and the BFL-1 transcriptional start site (TSS). Interestingly, both LCLs and germinal center light zone B cells shared similar chromatin architectures at the BFL-1 TSS, suggesting a conserved mechanism underlying BFL-1 upregulation. Increased BFL-1 in LCLs also protects against FasL and TRAIL-activated extrinsic apoptosis. In addition to BFL-1 expression, LCLs and germinal center light zone B cells share similar patterns of gene expression, suggesting strong evidence that EBV infection phenocopies various aspects of the germinal center reaction. From this, we infer that EBV-infected B cells co-opts strategies from germinal center light zone B cells to upregulate BFL-1 and enhance their survival in establishing long-lived latent infection.

Genome-wide analysis of chromatin accessibility in human tonsillar B cell subsets

Project description:We performed ATAC-Seq on three freshly dissociated human tonsils sorted to purity into the following B-cell subsets: CD19+ naïve (IgD+/CD38-), memory (IgD-/CD38-), germinal center light zone (IgD-/CD38mid/CD83+/CXCR4lo), germinal center dark zone (IgD-/CD38mid/CD83lo/CXCR4hi), and plasma cells (IgD-/CD38hi). We used these data to derive differentially accessible sites between B-cell subsets and relative to EBV-immortalized B cell lines (LCLs). These studies revealed similarities between LCLs and both DZ and LZ GC cells at the BCL2A1 (BFL1) locus that formed the impetus for further three-dimensional chromatin studies, which are the focus of the associated manuscript.
